Calculating boost pressures.

[nicks67ca]

I've combed over dozens of builds and dyno pulls on Camaro5 forum this thread:

Biggest variables are
Ported blower / snout
Ported heads
long tube headers
overdrive pulley

What are your cam specs? To hit your goal i think you'll need to be over .600 liff with 22.5% overdrive pulley.

The boost number is really "it is what it is" based the combination above. There really isn't a formula to use. My guess is your going to be 12.5psi - 14psi.

My LSA build has a goal of 700rwhp with 22.5% overdrive, ported heads, cam, welded and ported snout, 1 7/8" headers and good exhaust.
